I am not a resident of Switzerland. Can I open a company there and how do I do it?

I researched this and found an article about company formation in Switzerland on the SwissFirma website. It explains in detail the procedure for non-residents, the requirements for documents and bank accounts, as well as the nuances of the tax system. I liked that the materials are very structured and give a clear idea of what needs to be done to open a company without any unpleasant surprises.
